Are you dealing with a flood of unnecessary application notifications in a Slack Channel?

Use the slack web app and install this [Tampermonkey](https://www.tampermonkey.net/) script.
Then, update the 'appText' const and it will filter out messages based on the app's 'username' 

For the full app (tm) experience, run it in chrome like:
`nohup google-chrome --app=https://app.slack.com &`
